One of my favorite Apollo features was I could be in the middle of a deep comment section. Swipe back to the homepage, then swipe over into where I left off in the comments. I believe this was handled by edge swipes vs swipes from not quite the edge for up/down votes. No idea how it remembered location.
Love the app! Really made the transition to Lemmy much easier.
I think that was swipe forward right? You can either swipe back or forward and that was my my favourite thing about Apollo too.
For now I’m just happy that swipe back works. I’m sure one day swipe forward will be implemented!
